There's Bonnie and Clyde--then there's Martha and Ray. One-shot writer-director Leonard Kastle set out to make a film about lover-murderers that was everything Arthur Penn's movie was not. He succeeded. Consequently, The Honeymoon Killers, based on the Lonely Hearts Killers case of 1949, may be too lurid for some. But there's a heart beating inside its (tawdry) chest and Kastle clearly cared about these two crazy, mixed-up kids who should never have met. But met Martha (Shirley Stoler) and Ray (Tony LoBianco) did and proceeded to fleece several widows before doing them in. The film isn't graphic in its violence, but each murder is increasingly disturbing. Dramatic lighting and dark passages from Mahler keep the mood close and clammy throughout. Keep an eye out for Everybody Loves Raymond's Doris Roberts in a sharp cameo--and for shots directed by original helmer Martin Scorsese (fired for working too slowly). --Kathleen C. Fennessy
